Mica flake is the general name of mica group minerals. Mica minerals mainly include biotite, phlogopite, muscovite, lepidolite, sericite, phlogopite, phlogopite, etc. Muscovite and phlogopite are widely used in industry. Lepidolite is an important mineral raw material for lithium extraction. Here is mainly used for injection molding, coating mica.

Mica sheet has very high insulation, thermal insulation performance, good chemical stability, strong acid, alkali resistance and compression resistance, so it is an important raw material for manufacturing electrical equipment, so it can also be used as the insulation material in the blower. Mica sheet also has birefringence, so it is also an optical instrument material for making polarized light sheet.

Mica flakes are divided into natural mica and synthetic mica, among which there are many classifications. They are widely used. Their main physical characteristics are high insulation brightness. Synthetic mica is mainly used to solve the shortcomings of natural mica, such as not resistant to high temperature, strong acid, strong alkali and harmful chlorine corrosion. According to the composition and structure of natural mica, a variety of minerals (such as high-purity quartz, high-purity quartz, high-purity mica, high-purity mica) are selected High purity magnesia, potassium carbonate, etc. are mixed according to a specific proportion, heated, electrolyzed and melted at high temperature, and then cooled and crystallized.

Mica sheet can be used as raw and auxiliary materials for TV, power capacitor, thermal relay, monitoring display, aerospace, aviation, communication, radar, heat-resistant frame sheet, etc. Divided into: electric heater chip, electric heater shield, gasket, electronic tube piece, bulb piece, because its material is natural mineral products, with no pollution, insulation, good voltage resistance characteristics.
